HAND STAMPI.

Application led November 22, 1923. Serial No. 676,256.

To all @07mm t may concern:

Be it known that I, WILLIAM L. EDGAR- roi, a citizen of the United States, anda resident of Chicago,` kin the county of Cook and State of Illinois, have invented certain new and useful Improvements iny Hand p Stamps, of which the following is a specifi#y 'cation l This invention relates to printing devices but more particularly to hand stamps of the pad-i`nker type and has for its primary object to lprovide an article of this class which is simple and economical in construction and advantageous in use.

Further objects ot my invention are to provide an improved inlring pad construction and means .forattacliing the same to the frame7 and al novel and convenient method of marking the stamp to indicate at a glance the subject matter .ot' the imprint. y

Self-hiking stamps generally. have the inlring pad merely cemented to the under face of the top plate of the support or frame and this has )roven unsatisfactory as the pads frequent y become detached o-r displaced. In my improved stamp, the pad is securely faste-ned to the frame and accidental displacement or detachment will not` occur.

In this class of stamps the printing face is normally inverted and 4in contact with the inlring pad. Gn account of the difficulty of observing the type, it is common practice for the user to operate the stamp upon `a piece of paper to determine the nature of the imprint. I have rendered this unnecessary by securing a specimen of the imprint or other identifying matter on the upper face of the top plate of the frame where it may be readily seen at a glance.

The many other objects and advantages of my invention will be better understood by reference to the following specication when considered in connection with the accompanying drawing illustrating a selected embodiment thereof, in which Fig. 1 is a side elevation7 partially in section, of a hand stamp embodying the principles of my invention. n

Fig. 2 is a vertical section ot Fig. 1.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1, and

Fig. 4- is a detail perspective view of the inking pad construction.

on the line 2-2 Referring to the drawingQthe stamp coniprises 'the usual support or -frame 5, sta-nip bearing'member 6, handle 7, operating arms 8 connectingthe handle with the member 6, 50 guide post- 9. and spring 10 normally retaining'the member G in Contact with the face of the inking pad 11. The lower extremiities of the yarms 8 are connected by a pin 12 passing through vertical slots or guide-ways 13 in the Aside members 14 of the frame and the stamp bearing member is pivotally mountedy on thispin. This member 6`is inverted in the customary manner by tumbler blocks 15 secured upon the back thereof 70 and co-acting with pins 16 vand 17 projecty( ing inwardly from the side members of the frames .L kThe inlring pad 'comprises asheet metal back 18,v one or more layers 19 of ink-ab- ,75 sorbing noaterial7 anda cover 20 of suitable fabric which secures thelayers 19 to the back. This cover Ienvelops the sides and under face of the ink-absorbing material and its edge portions 21 overlie the upper 80 face of the back (Fig. 1i). Theseedge portions may be cemented to the back. Small lugs 22 are formed on the metal back 18 andr these are bent upwardly lat substantially a right angle to the upper 'face of the 85 back to permit them to be inserted through corresponding perforations 23 in the top plateof the frame 5. They pad is secured to the undery face of this plate kby thus inserting the lugsy 22 4and bending these lugs 90 inwardly (Fig. 3). I The pad may be detached from the frame by bending the lugs 22 to upright position;

y In addition to attaching the inkingpand to the framein the manner described, lthe lugs 22 act to secure an identification card 24 upon the upper faceof the-'top plate' of the frame (Fig. This card would prominently display an imprinty of the stamp or carry such information'regarding' the same 100 as would be necessary to provide complete identilication; The card is yprovided with a central orifice 25 to permit the guide post 9 to pass therethrough and this orice preferably is connected to one edge of the card by a slit, as 26, to enable the card to be installed or removed after the stamp 1s assembled. i

In order to protect the card, I prefer to cover the face of the same with a sheet 27 of 110 transparent material lsuch as celluloid and this sheet is likewiser held in place by the lugs 22, j This covering sheet is also 4provided with a central orifice, but there is no necessity for providing a slit as in the case of the card as the sheet is preferably installed when the stamp is assembledby the manufacturer and it is only necessary vto raise the sheet slightly to permit a card to be inserted or removed.

It will be readily evident that my' iniproved hand stamp is simple and economical in construction and advantageous in use. The pad is securely attached to the frame but may be quickly and easily detached for the purposeof renewal of the ink-absorbing material or cover. The identification card is conveniently placed and readily observed. It cannot become accidentally.detached as could a mere pasted label and is easily changed. c

I am aware that numerous changes may be made in the form and arrangement of parts without departing from the spirit of my invention, andI reserve the right to make all suoli as fairljT fall within the lscope of the following claims.

I claim as my invention:v

l. In a hand stamp, the combination with a supporting frame, of an inking pad mounted on said frame and comprising a back plate, means on said plate for engaging said frame, and ink absorbing material carried by said plate.

2. I n a hand stamp, the combination with a su a Jort-infr frame including ato late of l l as e: P P a an inking pad on the under face of said plate comprising a metal back, attaching means' on said back interlocking with said plate, and ink absorbing material secured to said back.- c

3. In a hand stamp, the combination with a supporting frame including a perforated.

top plate, of an inking pad on the yunder face of said plate comprising a metal back provided with attaching lugs inserted through thev corresponding perforations in said plate and having their extremities bent over to interlock with said plate, and ink f absorbing material secured upon the under face of said back.

t. In a hand stamp, the combination with asupporting frame-including a perforated top plate, of an inking pad 'secured on the f under face of said plate and comprising a sheet. metal back having yattaching lu s formed on the edges thereof and bent to su the corresponding perforations in said plate and their projecting extremities bent over to form an interlocking connection with said plate, ink absorbing material on the underface of said back, and a fabric cover for said material extending over the face thereof and having ils edge portions folded upon the upper face of said back.

5. In a hand stamp, a supporting frame in. cluding a top plate, and means for attaching an identification card upon the upper face of said plate comprising a plurality of meinbers overlying the said'face at an interval therefrom antico-operating therewith.

6. In a hand stamp, a supporting frame including a top plate, and means for attaching an identification card upon the upper face of said plate including a plurality of spaced lugs projecting from and overlying said face, the said lugs being adapted to engage the edges of said card. j

7. In a hand stamp, a supporting frame including a top plate, an identification card on the ,upper face of said plate, and a plurality of lugs projecting from and extending inwardly over said face for engaging the edges of said card at intervals to retain said card thereon.

8. In a hand stamp, the combination with a supporting frame including a perforated top-V plate, of an identification card and an inking pad respectively on the upper and the under faces of said plate, said inkingk pad comprising a sheet metal back provided with upstanding lugs projecting through the corresponding perforations in said top plate and having their free extremities bent inwardly over the edges of said card to attach said pad and said card to said plate, and ink absorbing material on the under face of said back.

9. In a hand stamp of the class described, an inking pad comprising a metal back, attaching lugs formed on said back, ink absorbing material on one face o-f said back, and a fabric cover enveloping said back and said material to retain said material on said face.
